The laptop does not find wifi networks windows 7. We solve problems with WiFi
Hello dear friends. As you probably already understood from the title, today I decided to touch on a very serious and painful topic, and try to figure out what to do when Wi-Fi does not work on a laptop or netbook and how to still connect a laptop to WiFi router. By the way, it can be not only a laptop or netbook, it can also be a regular desktop computer with a Wi-Fi receiver. There have been a lot of similar questions lately, mainly to the article.
Now we will try to figure out step by step what and why problems may appear when connecting a laptop to wireless wifi networks. We will also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, or rather an unsuccessful connection.
Most often, problems arise when you cannot turn on the Wi-Fi module itself on a laptop. And when Wi-Fi turns on, the laptop finds all available networks, but when you try to connect, it writes. You need to check if the drivers are installed on the Wi-Fi adapter, if Wi-Fi is enabled on the laptop, etc. Now we will do this.
I noticed that most often problems with connecting to Wi-Fi are found in Windows 7. It is on this OS that the error network without access to the Internet very often appears, I wrote how to solve this problem in the article, the link to which is above. In fact, as practice shows, there can be a lot of reasons for this problem. And if there are many reasons, then there are many ways in which you can make a laptop connect to a Wi-Fi router.
But it is not always the laptop, netbook, etc. that is to blame. There may be a problem in the access point, that is, in the Wi-Fi router. And the first thing we need to do when there is a problem with connecting to Wi-Fi is to determine what is the reason, in a laptop, or in a Wi-Fi router. Now I will consider the problem with connecting to my own router. Because if you are unable to establish a connection with someone else's Wi-Fi, then all claims are against the neighbor, it is most likely that he has problems :).
Who is to blame, laptop or Wi-Fi router?
As I wrote above, you first need to find the culprit. Before you make any settings on a laptop or Wi-Fi router, you need to understand what the problem is, which is why you can’t connect your laptop to Wi-Fi. You can just set it up so that you then have to do it and set everything up again. Most The best way to determine in which device the problem is hiding, it is to try to connect another device to the router, for example, another laptop, tablet, or phone. And a laptop that has problems connecting to Wi-Fi, you need to try connecting to a different wireless network.
I think that you understood my idea. If there are other devices connected to your router (best with similar operating system) will connect without problems, then the problem is in the laptop. Read this article further, now we will try to solve it.
Well, if problems when connecting to your network occur on other devices, and the “problem” laptop connects to other networks without problems, then the problem is in setting up the Wi-Fi router. See the article on, it might come in handy.
I will show on the example of a laptop that runs on Windows 7. This is currently the most popular operating system.
I advise you to immediately pay attention to the icon that displays the status of the Internet connection. It's in the notification bar.
If the internet connection status looks like this:
First you need to check if the Wi-Fi drivers are installed and if the Wi-Fi adapter is enabled.
Right click on "My computer" and select "Properties". Left select "Device Manager".
Open a tab in a new window "Network adapters" and see if there is a device like Wireless Network Adapter (Your name may be different). If you have such a device, then right-click on it and select "Properties". Another window will open, make sure it says "The device is working properly."
If everything is about the same as mine above in the screenshot, then everything is fine, the driver is installed. And if there is no Wireless Network Adapter device and you have unidentified devices, go to the website of your laptop manufacturer, download and install the Wireless Network Adapter driver for your model.
Learn more about installing and updating the driver for the wireless adapter -.
Dealt with the drivers.
Checking if Wi-Fi is enabled on the laptop
If the driver is installed, but the Wi-Fi module is disabled, then the connection status will be the same:
Usually the wireless network adapter on the laptop is turned on, but it doesn't hurt to check. Wi-Fi on laptops (netbooks) is usually turned on and off with a keyboard shortcut. On my ASUS K56cm, these are the keys FN+F2. But although when I press these keys, I get a message that wireless adapters are enabled / disabled, but nothing happens. Look for a key on your laptop FN and key with a picture of a wireless network. Press them at the same time.
Some laptops may have a special switch on the case that you can turn Wi-Fi on or off. For example on Toshiba Satellite L300 it looks like this:
Enable or disable the wireless Wi-Fi adapter in Windows 7
But the best way to check if the wireless network adapter is working or not is to go to the network control center and see.
So on the notification panel, right-click on the Internet connection status icon and select "Network Control Center and public access” .
Then select on the left.
Looking for connections “Wireless Network Connection”. If everything is fine and the Wi-Fi adapter is enabled, then it should look like this:
If the adapter is disabled, it will look like the screenshot below. Click on it with the right mouse button and select "Enable".
Using the methods described above, we must make sure that the status of the Internet connection on the notification panel is like this:
This status means “No connection - There are available connections”- this means that the Wi-Fi adapter is turned on and there are available wireless networks for connection.
If the connection status is like this:
This means that Wi-Fi is on, but the laptop simply does not see networks available for connection.
Error “Windows could not connect to…”
We figured out the problem when the wireless network module is disabled, or does not work at all. Now consider the case when the laptop finds available Wi-Fi networks, but when trying to connect to Wi-Fi it says: “Windows could not connect to…”, where instead of dots is the name of the network you want to connect to.
If you have a network connection status such as in the screenshot above (via one, network with yellow icon), then click on it, and you will see a list of networks available for connection.
Select the desired network, click on it, then click the "Connect" button.
If the set is password protected, then Windows will ask you to enter a password. Write down the password for the network and click "OK".
And if everything is fine, then your laptop should connect to the Internet via a wireless connection. And the Internet connection status should look like this:
But it is at the moment of connection that the error "Windows could not connect to ..." very often appears. It looks like this:
Unfortunately, friends, there is no definite solution to this problem. But I can download that very often the problem with such an error appears due to WiFi settings router. Maybe through the type of security and encryption that is installed on the Wi-Fi router, read more about this in the article. There may also be a problem with the distribution of IP addresses.
If you notice, then in the window with the error "Windows could not connect to ..." it is possible to run “Troubleshooting”, sin not to use. Try to run it, I heard somewhere that there are cases in which it helps :). But seriously, sometimes it really helps. Windows will check if the wireless adapter is ready, check settings, etc. And if it can, it will fix the problem that is preventing you from connecting to Wi-Fi.
Just reboot the router and then the laptop. Very often this helps.
Update
I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I'll explain now.
For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters no longer match, that's the error.
It is enough just to delete the network on the computer and re-establish the connection. I wrote about it in an article
Conclusion
Great article turned out, and I hope that it is useful. I wrote it for half a day, intermittently, of course, there were still problems with adding screenshots to the site, but I sort of solved it.
I tried to collect all the necessary information that should help you solve the problem that occurs when connecting a laptop or netbook to Wi-Fi. If I forgot to write something, then in the future I will definitely supplement the article, I will also be very grateful if you share information in the comments that helped you solve the problem with connecting to a wireless network.
If you have any questions, then ask them in the comments, we will try to figure it out. Best wishes!

Why doesn't Wi-Fi work on a laptop (netbook)? How to connect a laptop to a Wi-Fi router? Error “Windows could not connect to…” updated: February 7, 2018 by: admin
- Introduction
- 2 main situations when you can not connect to wi-fi
- Reasons why the laptop may not see the wi-fi network
- Ways to Fix No Wi-Fi
- Conclusion
Welcome friends. In this note, we will consider why the laptop may not see the wi-fi network. To begin with, it’s worth figuring out (albeit briefly) what wi-fi is, what its principle of operation is and what it usually requires for this.
So if you say in plain language, That wi-fi is nothing more than a wireless way to connect digital devices. It is important to understand that with it you can not necessarily go directly to the Internet, it's just a way to build wireless networks (like bluetooth, for example).
In order to access the Internet, this wi-fi network must be connected to a router (special modem), which, in turn, provides access to the global web (via telephone, network cable or in any other way).
It follows from this that if your device (laptop, phone, tablet) has a Wi-Fi connection, then this does not mean that it will immediately connect to the Internet (maybe this will seem obvious to someone, but some users may think that way ).
2 main situations when you can not connect to wi-fi
- The reason is in your device
- The problem is in the wi-fi network (that is, in the modem on which this network was created)
In order to eliminate problems in your laptop, you need to connect to an existing wi-fi network from another device, for example, from your friend's phone. To do this, as usual, take a smartphone (tablet, beech) from him, search for available Wi-Fi networks and connect to the one you need.
As a result, if your router is configured correctly, your friend’s smartphone connected immediately and without problems, then you should look for the reason in your device (more on this below).
In the second case, you are sitting alone (or with a company) and cannot connect to a wi-fi network, for example, in public place. It is correct, perhaps it was simply turned off or access was limited (for example, by the number of simultaneously connected devices). In such a situation, you need to contact the administrator. Or, if there are problems with the modem (your, not your neighbor), then you need to either reboot it or reconfigure it.
That is, the first step is to decide where the malfunction is, and then delve into its solution.
Reasons why the laptop may not see Wi-Fi
Now let's take a closer look at the main points why there is no connection to the Wi-Fi network:
- To begin with, it is worth noting whether Wi-Fi is enabled in the "beech". This is easy to check, at the bottom near the clock, click the corresponding icon. If no available networks appear there, then most likely it is disabled.
- Connection failed. This can be most often due to modem errors. You can simply reboot or reconfigure it. To do this, just look at your modem and find the wi-fi indicator - it should be on.
- Is the driver installed and what is its version on the laptop. Very often, if the "beech" is new or the operating system was reinstalled on it, then the installation of the necessary driver for Wi-Fi is required. If this is not done, then you will not be able to enter the network.
- Wifi stopped working on laptop. The reason may be a breakdown of the corresponding adapter inside the device. Here only repair with its replacement.
- Run out of money on the internet. In such a situation, by itself, you won’t be able to access the Internet via Wi-Fi. You just need to put money into the account and the problem will be solved.
Conclusion
As you can see, there can be quite a lot of reasons, we have considered only the simplest and most popular ones. No need to take it lightly simple ways solutions such as checking the funds on the account or restarting the laptop, very often they help to solve the current problem.
It is worth starting with the information presented above, and then moving on to deeper and more individual solutions to your issue. This concludes the solution of the question why the laptop may not see the wi-fi network, what to do in the first place in such a situation. Thank you for your attention, if you have any questions, then write them in the comments.
If you got a brand new laptop or your existing device stopped seeing available wireless networks, if after the next reboot or the next update of Windows and the driver your device stopped connecting to Wi-Fi, if you observe some difficulties when searching for a network or connecting to them, then this article is what you need. In it, we will analyze the most effective methods, which will help eliminate the incorrect operation of the equipment and explain why “the laptop does not see Wi-Fi” and “an error appears when connecting to a Wi-Fi network.” Let us consider other questions related to the correct Wi-Fi operation on a laptop.
Solve a detection problem WiFi networks you can do it yourself
Below we present detailed instructions to troubleshoot various problems. But the first thing to do to find out the reason why the laptop does not see the Wi-Fi network is to identify the source of the problem. Several components are responsible for the correct operation of the Internet connection and the Wi-Fi connection of your computer:
- A wireless router that is responsible for the direct creation and operation of the network.
- A network adapter built into a laptop that is responsible for receiving and processing the signal sent by the router.
- Drivers and software, ensuring stable and correct operation of the network adapter.
If at least one of these components does not work as it should or does not work at all, the laptop will not see the Wi-Fi network or simply refuse to connect to it. Consider what needs to be done in order to identify the source of the problem. Knowing at what stage the snag occurs, you can proceed to troubleshoot and provide your computer with a quality Internet connection.
First of all, we recommend checking if Wi-Fi is activated in your laptop and whether it is ready to receive a signal. You can do it different ways. The most obvious one is to find the wireless icon on the keyboard and activate the network adapter. The thing is that in most laptop models, to save battery power, Wi-Fi is quickly turned on and off. To do this, there is a button with the corresponding icon on the keyboard. On some models, this is the F2 or F3 key, which must be pressed at the same time as the Fn function button. And in some models, a special toggle switch can be built in, which is located on the side panel or at the top of the keyboard, separately from the main set of keys.
If a specific laptop model does not have a key to activate Wi-Fi, you can do this in the Windows Control Panel. To get started, follow this path: Start > Control Panel > Network and Internet > Network and Sharing Center. A new window will open in front of you, where you need to pay attention to the column on the left. Find the item "Change adapter settings" in it and click on it. You will see all adapters and network connections that exist on your device.
Find “Wireless Network Connection” among them and see what is written right under its icon. If the status is "Disabled", then you need to right-click on the connection and click on the "Enable" item in the drop-down menu that opens. After that, go to the system tray in the lower right corner of the display. The icon of the active wireless adapter will be displayed there and by clicking on it, you can search for Wi-Fi sources.
Checking the router
The next step is to check the router. The simplest and effective method check the operability and correctness of the router settings - connect another device to the target network, which will become an indicator of correct or incorrect operation. If another computer, tablet or smartphone connects to the Internet without any problems using the selected equipment, it will be quite easy to conclude that the router is working correctly, and the problem most likely lies in the laptop and its components. Software or hardware - we'll figure it out a little later. If the connection does not occur or the access point is also not visible on other devices, then it is worth re-configuring the router or diagnosing it.
There are times when a laptop sees available networks (neighboring offices, apartments, etc.), but your access point is simply not on this list. In this situation, we recommend that you search in close proximity to the router. This is necessary in cases where the device is new and recently configured. Perhaps its settings or location do not allow broadcasting a signal to the required distance, while in close proximity it can work flawlessly. In the event that the laptop sees the desired network in close proximity to the router, you will need to check the settings of the latter.
Checking and installing the driver
What to do if all the previous steps were completed, but the laptop did not see the available Wi-Fi sources, we will consider in this section. In the case when the network adapter driver is not installed, does not work or does not work correctly, you can see the corresponding icon in the system tray - the monitor and cable icon crossed out with a red cross. In this case, do the following:
- open the properties of your computer by right-clicking on the corresponding icon on the desktop;
- a new window will open in front of you, in the left column of which you can find "Device Manager". Run it;
Among the "Unknown devices" may be the required network adapter
- in a large list with nested items and big amount categories, find Network adapters;
- since there are usually several of these same adapters in your PC (wired and wireless), find the wireless one among them. Most often, it is listed as Wireless Network Adapter or a derivative of a similar phrase;
- click on this line (you also need to do this with the right mouse button) and in the drop-down list that appears, select the very last item - “Properties”;
- you will see the system properties window of the adapter. Check it for the status indicated in the “Device Status” item. If the status differs from "The device is working normally", this indicates the incorrect operation of the driver or its complete absence. This happens after a system reset. In this case, you will need to visit the official website of the manufacturer and download the driver for the Wireless Network Adapter designed specifically for your model on the support page.
After installing the wireless adapter driver, you must restart your computer. After turning on the computer, go to the "Control Panel" again and check the status of the device again by opening its properties. Now the status should sound like "The device is working properly" - this means that you can start searching for available networks and connecting.
Why does the laptop not see Wi-Fi? Access points are almost everywhere. But there is no way to connect to the Internet. Because the laptop seems to be "blind". Everything seems to be done right.
The necessary settings have been made. The computer is deaf. Why?
The laptop does not detect wireless Internet: why?
Many people have faced this problem. The most annoying thing is that a failure could happen at any site, at any link. Popular routers that people use to connect today are configured in much the same way. From the side of the laptop, certain actions are also required, almost completely identical for all models.
Reasons for not detecting wireless networks:
1) Your router is not configured to receive a signal, it is turned off for some reason, it starts to fail or freezes;
2) The reason lies in the computer; the appropriate settings have not been made, the hardware slider or the wireless connection button is disabled (it is usually located on the case);
3) The Internet is not paid or the provider disconnected it for other reasons;
4) The owner of the access point to which you are trying to connect unauthorized (without permission) is blocking your connection;
5) Antivirus program blocks the World Wide Web;
6) The IP address was not entered automatically.
There are many reasons. We will not explain situations when the provider restricts your actions or you are trying to connect to a "foreign" No. In such cases, issues need to be resolved with the help of money or personal charm. And here all the instructions are useless.
Finding a Solution
Why does the computer not see the flash drive? The reason may be in the computer, and in the flash drive. The same is true with wireless internet.
To solve a problem, you need to classify it. On which part of the link did the failure occur?
1. The router does not receive a signal, does not let the Internet.
2. The laptop does not connect with the signal transmission device.
3. The signal is on, the computer sees the network, but it is still impossible to enter the Internet. For some reason.
Problem number 1. The router is not working.
The easiest way to make sure that it works is to connect the laptop to it via network cable. If everything is fine with the router, the Internet connection will happen.
External signs of device inoperability:
a) the corresponding indicator on the case is “silent”;
b) is missing in the administrative panel in the WAN Internet connection tab.
What can be done?
1. Turn off and turn on the router (suddenly it freezes).
2. Check if the router and network card are turned on.
3. Check the connection settings to the provider. If necessary, re-enter them manually.
4. Call the provider and ask if everything is in order with the network.
Problem number 2. The laptop does not connect to the router.
The receiving device is working. Other computers, smartphones, phones, and the like see the router. A specific computer does not see anything.
1. We check the network connection on the computer (in the "Network Connections" tab).
2. Check the settings of the router and laptop. Through the "Control Panel" we find the network interface responsible for the connection. The path to it in different versions of the operating system is different. But usually the adapter is labeled as "Wireless Network Connection". We go to "Properties" and find the protocol of the Internet version. We go back to "Properties" and check if the IP address, default gateway, subnet mask is specified. Perhaps this data was not entered at all. Then we enter them (they are obtained from the router).
3. We check on the device case whether the corresponding button is enabled.
Problem number 3. The laptop sees networks, but the Internet does not work.
1. Reinstall the Wi-Fi transmitter drivers (they are available on the laptop manufacturer's website).
2. Check for auto-transition to "Sleep Mode". This setting often gets in the way. Therefore, automatic transition to sleep mode must be disabled.
3. Making Wi-Fi a safe network for a computer. Perhaps the firewall perceives it as a threat, and therefore does not let it in. The procedure can be performed through the "Network and Sharing Center". We go there and simply select the desired network.
Try turning it off while checking. antivirus program. Perhaps the problem is with her. Any of these methods should help.
Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve the problem of connecting to the Internet without using conventional wires. This is especially true in the case of using laptops, with the help of which you can access the Internet in any convenient place due to the presence of a built-in Wi-Fi adapter.
That is why the situation when Wi Fi does not work on a laptop leads to significant inconvenience and even some problems. There are many reasons why Wi-Fi may not work on a laptop computer. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of those that can be completely eliminated on your own. Let's consider them.
Problem with laptop or router?
A fairly common problem that a laptop has stopped connecting to a WiFi network is not a problem with the laptop itself, but with the settings of the router, which distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on precisely because it has nothing to connect to.
To eliminate the possibility that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter - from another laptop, smartphone, tablet, and the like.
If Wi-Fi does not work from another gadget, then the problem lies precisely in the Wi-Fi router distributing the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.
Hardware enable adapter
Based on such diagnostics, you can accurately determine that this problem arose precisely through the fault of the laptop. When Wi-Fi does not work on it, you can try using several methods.
The first one is to check if the wireless connection adapter is enabled on the laptop. Almost all modern models have light indicators of the WiFi module operation and there are special key combinations for its hardware activation.
Usually, a lit indicator indicates that the module is on. If the indicator does not glow at all or shines in red, then the Wi-Fi does not work precisely because of the wireless network adapter. It needs to be enabled.
Most often, such indicators are located directly on the keyboard, side or front panel of the device. Sometimes they are located on the monitor case or near the touchpad.
To enable the module of such a network, press the key combination Fn and one of the system F1-F12. The specific combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to enable Wi-Fi, you should try pressing the combination standard for a particular model:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.
After pressing the appropriate keys, we check whether the indicator of the wireless connection module lights up or whether it stops glowing red. After that, you should try to connect to the network again. If this does not help, go to the next step.
Software inclusion
When Wi-Fi stopped working and its hardware inclusion does not work positive results, you also need to implement its software inclusion, which is carried out directly from the operating system under which the laptop is running.
To implement software turn on wifi, which stopped working, on Windows 7, 8 or 10, you need to perform the following sequence of actions:
1. On the notification panel, which is located near the clock, the network connection status icon is selected;
2. From the list that opens, select the "Network and Sharing Center" or "Network Settings" item, depending on the version of the operating system;
3. The next step is "Change adapter settings".
Among the list of all existing connections, you need to pay attention to the color of the "Wireless Network Connection" icon. If your WiFi does not work and the wireless adapter is disabled, then the connection icon will not be highlighted. In this case, right-click on its icon, select the “Enable” item from the context menu that opens. In this case, the color of the connection icon should change.
At the same time, the wireless network adapter turns on, it remains to find the desired one in the list of available wireless networks and connect to it.
If, after such actions, Wi-Fi, which has stopped working, continues to be inactive, you need to move on to the next method to solve the problem.
Installing and updating the driver
Quite often, the Wi-Fi wireless connection does not turn on due to the lack of a driver or when it is very outdated. To determine the presence of an installed driver, you need to select the "Properties" item from the context menu of the "My Computer" icon, which is located on the desktop or in the "Start" menu. Next, in the window that opens, select the "Device Manager" command from the menu on the left.
In the new window that opens with a list of connected devices, you need to find the name of the laptop's wireless network adapter. Usually its name is “Wireless Network Adapter” or “Wireless Network Adapter”, along with which the manufacturer of the device should be indicated: Realtek, Atheros, Qualcomm, or something else.
Having found the desired item and clicking on it with the right mouse button, "Properties" is selected from the context menu. In the window that opens in this case, the item "The device is working properly" should be present. But even if there is a mark about normal operation device, this is far from a guarantee that the installed correct version drivers and Wi-Fi turns on correctly. To check it, in the window with the properties of the wireless device, go to the "Driver" tab and pay attention to the items "Date of development" and "Vendor".
In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.
The same must be done if there is no wireless adapter in the list of installed devices.
If the wireless module is present in the list of devices, but marked with a yellow exclamation point, this means that the device is disabled, as a result of which the network has stopped working. In this case, having opened the device properties window, you need to click the "Enable" button.
Another reason why Wi-Fi stopped working on a laptop may be that the power saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the "Power" icon;
3. In the window that opens, select the "High performance" or "Balanced" mode.
External signal obstructions
It should also be noted that the non-working wireless network can also be the result of more than just problems with the laptop. The wireless connection signal depends on some external factors which can weaken it. Ceilings, walls, floors, and similar obstacles significantly degrade the signal quality of the access point and laptop.
As you know, the signal quality on a personal computer is displayed in the form of several marks - the more there are, the better the signal is. If the wireless connection level is displayed as 1 or 2 marks, then you can not try to use WiFi - in this case, it will not work properly.
In this case, you need to move the router closer to your workplace, move workplace closer to a Wi-Fi router or buy a new, more powerful router.
Other causes of Wi-Fi problems
The causes of problems with the functioning of the wireless network adapter described above are the most common and you can fix them on your own.
It is worth noting that all these are software methods for solving the problem, which will be solved by installing, reinstalling or updating the device driver, as well as performing some operations with the OS.
But often the problem with the operation of the wireless connection module lies in hardware errors. What are these errors? These are problems that are directly related to the board itself, most often - its physical damage.
To fix such problems, you will need to disassemble the laptop. It is worth noting that such actions can only be performed if you have certain skills in this area. If such skills are not available, it is better to entrust the work to professionals.
One of the most common physical damage is an unconnected antenna wire to the proximity module. This problem occurs with laptops that were under repair or if their owner cleaned the cooling system from dust on their own. In such cases, the antenna is sometimes simply forgotten, as a result of which the adapter will not be able to establish a connection even near the signal source itself. To fix this problem, you just need to connect its antenna to the Wi-Fi module.
Sometimes the reason that Wi-Fi stops working is the usual overheating of the network card. Most often this is the result of the fact that the laptop is on one or another soft surface. The thing is that at the bottom of the device there are holes through which cold air enters, cooling all the computer boards. By blocking these openings, the system will overheat, which can lead to the failure of certain components.
Another common cause of device overheating is dust, which can prevent cold air from entering the cooling system.
That is why, in order not to encounter such problems, it is recommended to clean the laptop from dust at least once every year: in this case, it will be possible to avoid repairing the laptop as a result of overheating of its components.
In the most neglected cases, the wireless adapter may even burn out. In this case, only replacing it with a new one will help. You can determine such a problem using the device manager, in which the module will simply cease to be displayed. When you try to install a driver for a wireless network, a message appears stating that the corresponding device is not installed in the system.
If nothing helped
If none of the tips above helped, you can use a simple, but at the same time often effective solution: restart both the computer and the wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function that is in operating system Windows.
Thus, most of the existing solutions to the problems associated with the fact that Wi-Fi stopped working on a laptop were listed above. Almost all of these methods and recommendations can be used by anyone who has encountered a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one way out - to go to a quality service center for help, where they can solve any problems with a laptop.
